I am not sure were to link too? But here is the bbs.
http://www.huskermax.com/vbbs/forum.php
This is a sports site with Football being the most poplar. So during the football game is when the server slows down. there seems to be a mass connection at the start of the game and the bbs runs slow through out. the server load/bandwidth use shoots up. But when there is a slow run up to 400 connections the board does fine. It is this sudden mass connection I am guessing. Regardless it sounds like this should not be doing this. The whole website is getting about 100,000 page views a day.
I know 400 or more on the BBS but I can't tell how many people may be viewing the website.
What info is needed to help you help me figure this out?
